In the blood-soaked northwest wasteland, the lively and hearty Bai Sanniang encountered a disaster. In order to seize the water source in the village, the warlord Yan Yihu killed his husband Zhao Tieshan and skinned him to show the public. After witnessing the tragedy, Bai Sanniang lost all the warmth in her heart, leaving only deep-rooted hatred. She tightly grasped her late husband's gaping waist knife and vowed to pay with blood.
From then on, the name "Blood Rakshasa" resounded throughout the northwest. Bai Sanniang gathered in the mountains and forests, gathered the remnants with ruthless tactics, and established the iron law of "three no-grabs" to protect the poor and weak, becoming a twisted barrier in troubled times. However, every night late at night, the female bandit leader was choked by the nightmare of the sea of blood. The scene of her husband's tragic death and the bloody touch of the blade repeatedly tortured her, making her unable to sleep at night. She could only accompany her with strong alcohol and a polished knife.
The gears of fate are turning when Yan Yihu's arms train is plundered. Bai Sanniang accidentally discovers an old photo, which reveals that Chen Ergou, her husband's best friend back then, is actually Yan Yihu's lieutenant today. The betrayal of a close relative is the root of the trouble. At the same time, the mysterious and downtrodden "Old Zhou" joins the cottage, bringing the spark of revolution in the south. His extraordinary conversation and the fire in his eyes quietly stir up Bai Sanniang's dead heart, triggering a fierce collision between the cottage's rules and new ideas.
When Yan Yihu's army presses the border, the end of revenge and the survival of the village come at the same time. In the light of the fire, old and new hatreds surge, brothers are bathed in blood, and the fortress is about to collapse. The seriously injured "Old Zhou" thrust the arsenal map that was related to the lifeblood of the northwest into her hand, and screamed: "Destroy it! In order not to have the next Zhao Tieshan, the next Bai Sanniang!" Standing on the burning ruins, Bai Sanniang looked at the raging enemy troops and the faces following behind her. Her knife once only drank blood for revenge, but now it carries a heavier mission...
